sound transducer 中文意思是什麼

sound transducer 解釋
電聲換能器
  • sound : adj 1 健全的；強壯的，正常的；完好的，無疵的，沒有腐爛的（船、牙齒等）。2 正確的；正當的，合法的...
  • transducer : n. 【無線電】轉換器；換流器，變頻器；換能器，轉換裝置；發送器；傳感器。
  1. Because this transducer not only has a firm structure and uses the longitudinal mechanic - electricity coupling coefficient of piezoelectric crystals, but also can be easily made, it has very good electricity - sound ability

    由於製作工藝簡單，結構堅固，且又利用壓電陶瓷的縱向機電耦合系數，因此具有良好的電聲性能。
  2. Compared with the pressure hydrophone, vector transducer can provide both the information about pressure ( scalar quantity ) and particle velocity ( vector quantity ) of the sound field, which offers more possibilities for signal processing. so vector transducer and its signal processing have attracted the attention of researchers both native and foreign. in this thesis, a method of correlation equations for pressure gradient transducer is presented, and the estimation of multi - signal parameters with single vector transducer is given

    與傳統的聲壓水聽器相比，矢量水聽器既能獲得聲場中的聲壓這一標量信息，又能獲得聲場中質點振速這一矢量信息，這為其信號處理帶來更大的空間，因此矢量水聽器及其相應的聯合信息處理技術日益成為國內外科技工作者們研究的熱點。
  3. For sound pickup, acoustic processing aims at the design of transducers or transducer arrays to achieve a durable directionality ( beam steering and width control ) as well as noise resistance

    對于拾音，聲學處理的目標是設計耐用的指向性（束調整和寬度控制）及抗噪聲換能器或換能器陣列。
  4. A discussion on the receiving signal of transducer in experiment of sound velocity measurement

    聲速測定中換能器接收信號探析
  5. It was demonstrated that this sort of load - control apparatus has superior performance. we used a electric transmitter as the transducer to collect the sound signal, using the daq toolbox of the matlab to achieve the collection of the sound signal, and using the dsp toolbox of the matlab and the sound - launch technology to analyze the time - domain characteristic and the frequency - domain characteristic of the signal, chiefly analyze its short - time average amplitude, its short - time over - zero ratio and its estimate of the power chart and the average - period chart

    實驗中使用了駐極體話筒作為球磨機聲音拾取傳感器，利用matlab中的數據採集（ daq ）工具箱實現對磨音的採集，利用matlab信號分析（ dsp ）工具箱和聲發射技術對磨音進行時域和頻域分析，主要分析磨音的短時平均幅度和能量、短時平均過零率、功率譜估計和平均周期圖。
  6. Therefore, the piezoelectric ceramic with desired structure and properties can be obtained by introducing pms materials and pzn materials into pzt materials, which has great potential of being widely applied in many fields, especially in advanced sound - electricity transducer

    將二者共同引入pzt結構，可獲得較為理想的綜合性能。這種材料在諸多應用領域都有著較好的應用前景，在聲電換能器方面的應用前景尤為受到人們的普遍關注。
  7. But the sound field generated by this kind of transducers in medium has s ome " congenital " shortcomings : there always exist zero areas in sound - axes of near - field however we change the frequencies and radii of transducers, so we need to look for better radiate transducers. in this dissertation, we design and make two kinds of radiate transducers : bunchiness control transducer with electric polarity division and gaussian transducer

    然而，這種類型的換能器在媒質中產生的輻射聲場，有其「先天性」的不足之處，在近場中無論平面活塞的頻率和半徑如何變化，軸上和沿徑向上都呈現出極大和極小交替分佈的干涉現象，因此我們有必要繼續尋求更為理想的輻射形式。
